Abstract：Toaddress thechallenges of adapting tomulti-model aircraft extermal trackingand positioning incommercial aerospace launch sites，this paper designs and implementsauniversal external trackingand positioningsystem basedonstate machinesandpre-configuration.Throughpre-configuredXMLfiles，thesystemstandardizestelemetryframeformats，xteral tracking channel positions，and positioning frame structures，automates frame extraction with O（n） complexity via state machine technology，andreducesprocesing latencythroughmulti-threaded parallelcomputing.Itadopts thelayeredarcitecture （infrastructure，configuration，business，and application layers）anda“platform + plugin” model.It enables thedynamic generationofcapabilities fortelemetrysynchronization，channel selection，frameextraction，andpositioningcalculation.Tests demonstrate that the average time delay of positioning calculation is 4.9ms ，thepeak CPU occupancyis 13% ，andthe peak memory occupancy is88.167KB.The system has been successfullyadapted to five distinct aireraft models，significantly enhancing mission adaptability and real-time performance of external tracking and positioning system.
